Visualizing Repository Activity

I am updating the
lessons learned paper,
and would like to include histograms showing how many people have contributed how often to our lessons.
More specifically,
I have 9 data sets (one for each lesson),
ranging in size from 5 to 16 records,
in which each record shows a number of commits and how many people have committed that often.
For example,
the data for our SQL lesson is:

meaning eight people contributed once,
eight contributed twice,
and one contributed 106 times.
What's the best way to visualize this,
given the spread of values on the X axis?
And what's the easiest way to generate that visualization in Python?
(You can get the data here to try out your ideas.)
